rsync keeps causing kernel crashes

Hi all. I've been running rsync both locally on the same machine for redundancy, and also across a WAN link on Fedora 10. Periodically, the kernel will crash and lock the machine. I can't see any pattern to this except that I've observed it occuring with certain .zip files, and the occasional large .pdf. Any ideas as to why this keeps happening, and how I can prevent it? Is anyone experiencing similar behavior? By the way, syncing is done twice an hour to keep the load as small as possible, and I use the -avzsu options.

Hi there,

I have been trying to figure out rsync for months now. I have 150GB to backup from windows to my linux server and it gets around the 3GB mark then dies on me too.

I use ssh to connect but I dont get any errors just a hang on the command line.

In my many nights searching the web I have come to conclusion that rsync can be very buggy.

I'm hoping others can prove me wrong.

Good luck if you find any solution. You're not alone out there with this!!

Fusion, thanks for the input. I'm not using ssh, because I'm syncing across a WAN link via VPN, so I'm letting the tunnel handle encryption. I am, however, using -avzsu options, so I think there's enough going on in rsync itself. I never calculated a failure point in terms of data amount, but I have noticed that since I cron'd the syncing, I'm sending far less data back and forth, and concurrently, I'm experiencing fewer crashes. I'll have to track the data amount more closely to see if that's a contributor.
